Great concept — that is exactly how I sift through the daily deluge of data: Information Triage:

n. The process of gathering, sorting, and prioritizing information to identify what is relevant or important and to discard everything else.

Information triage is the continuous process by which we refine the information we gather, paying most attention to the information that is most valuable and identifying additional information we want to procure.
